ATTORN EY Vat Patented July 9, 1935 PATENT OFFICEU i Samuel L Bergera'ewark, N. `.Ir e Appu'tiiyiifneiiqterf13,iesafseriai No. 757,3`os- 3 claims; g- (o1. 25e- 122) Y rlhis invention" relates to devicesfespecially adapted for mixingV various liquids, such as maltedV milk, iced drinks, leggnog, or for beating various substances, such as whipped cream, eggs or the like.

Heretofore in devices of this character,` the mixing means have been operated by a spring motor provided in a casing positioned above-the receptacle in whichthe substances being mixed were placed. In order to prevent the substances being mixed from rising into the casing containing the spring motor, it is necessary to provide a baffle plate, which generally is made of some thin metal. I-Ieretofore, such baiiie plates were susceptible of being easily bent during the rapid or careless attaching of the mixing device to a receptacle such as a glass jar; and when the baffle plate became bent, it soon ceased to function as an effective barrier to prevent the liquids and other substances being mixed from entering the casing containing the spring motor.

It is, therefore, an object of this invention, to provide a mixing device having a baille plate provided with reenforcing means to prevent it from being easilybent and at the same time enabling the ymixing device to snugly fit into receptacles such as glass jars and the like.

A further object is the provision of va novel construction for assembling a casing containing a spring motor and a baffle plate.

These and other advantageous objects, which will later appear, are accomplished by the simple and practical construction and arrangement of parts hereinafter described and exhibited in the accompanying drawings, forming part hereof, and in which: f

Fig. l is a view showing the manner in which my mixing device is applied to a receptacle,

Fig. 2 is a cross sectional View showing the mixing device attached toa receptacle, Y

Fig. 3 is an exploded elevational view showing details of the mixing device,

Fig. 4 is a sectional view taken on the line 4-4 of Fig. 3, and v Fig. 5 is a sectionalview taken on the line 5-5 of Fig. 3.

Referring to the drawings, my device is shown to comprise a casing 6 in which is contained a spring motor of a well known type, the latter being connected with an upper winding shaft 1 attached to a knob 8. An operating shaft 9 is attached to the lower part of the motor and projects through a bottom supporting plate I0 and is provided at its lower end with a stirrer I I. Depending from the plate I0 is a reenforcing cup-shaped .member I2 which engages a baffle plate-I2, the latter lbeing shaped according tothe form or shape ofthe bottom of the cup I2, said baille forming substantially the lower plate of the casing 6. Fixed to the cup I2 and to the baille plate 5 I3 is a bushing I4 through which passes the shaft 9, the bushing providing a substantially water-tight joint to effectively prevent liquids from moving upwardly into contact with the spring motor. any liquid does rise above the bushing I4, it will be held in the cup I2 and not rise as high as the supporting plate I 0 upon which the spring motor is mounted.

Y The baffle plate I3 is of sufficient diameter to 15 fit a standard sized mouth of a receptacle I5.

In assembling my device, the spring motor is Vmounted upon the plate IIl and the cup I2 is attached to the plate II). The casing 6 is formed with a flange I 6 while the baffle plate I3 is formed 20 with an upstanding flange I1. The plate I0 is brought into contact with the baffle plate I3 and the casing 6 is placed so that flange I 6 rests upon the plate IIJ andabuts the flange I1, after which the flange I1 is spun over the flange I6, 25 as shown in Fig. 2, to securely hold the parts together. This method of assembly obviously is very simple, and at the same time provides a compact and sturdy structure.

The spring motor enclosed in the casing is 30 provided with a winding spring I8 which is connected to the winding shaft 1, the latter having fixed thereto a gear I Il in mesh with a pinion 20 attached to a small shaft 2I upon which is mounted a gear 22 in mesh with pinion 23 at- 35 tached to shaft 24 on which is mounted a large gear 25 engaging the pinion 26 to which is attached the shaft 9. The structure of the spring motor isV common and well-known in the art.

In operation, the spring motor is wound by 40 means of knob 8 and winding shaft 1, and the brake 21 is moved to an out-of-the-way position to allow free rotation of the pinion 26 through which rotary movement is transmitted to shaft s and stiffer n.

From the above description itwill be seen that I have provided an unusually compact and simple structure which is rigid and not susceptible to being easily bent or distorted.

The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as restrictive or limitative of the invention, of which obviously an embodiment may be constructed including many modifications without departing As Will be seen, in the event that 10 from the general scope herein indicated and denoted in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a mixing apparatus, a receptacle containing the substances being mixed, a stirrer positioned in the receptacle, a spring motor for rotating the stirrer, a casing in which the spring motor is positioned, a plate on which the motor is mounted, said casing having a ilange'resting upon the plate, a reenforcing cup-shaped member depending from the bottom of the p1ate,a baille plate having a portion shaped to .conform with and engaging the cup-shaped reenforcing member, said baille plate having another portion shaped to t Within and engage kthe receptacle and a third portion resting upon the receptacle, and a flange projecting upwardly from said baffle plate, said flange being spun over the flange on the casing, whereby the baille plate and the motor supporting plate and the casing are positively secured together.

2. In a beverage mixing apparatus, a. supporting plate, a spring motor mounted on the plate, a. casing having a flange resting on said plate, a reenforcing member depending from the bottom of said plate, a baille plate having a portion shaped to conform with and engaging said reenforcing member, and a flange extending upwardly from said baille plate, said flange being over the flange on the casing and the supporting plate to securely Ahold the parts together.

3. In a. beverage mixing apparatus, a supporting plate, a. spring motor mounted on said plate, a casing covering said spring motor and having a flange resting on said plate, a reenforcing member depending from said supporting plate, a barile plate, having substantially the same shape as and engaging the reenforcing member, said baffle plate having a portion adapted to engage the inner walls of a receptacle, and an upstanding flange on said baille plate, said ilange being bent over the flange on the casing to secure the parts together.
